Hi,

I see you added the missing "exit" after the sl_send_reply() and you do create the dialog for each INVITE (hopefully only for the initial ones :) ).

What seems to be the exact problem now ?

hi,Schneur.
Thanks for your advice.
But I did put the check before create_dialog("B") in the original oprnsips.cfg:
if (is_method("INVITE")) {
                xlog("active dialog is $stat(active_dialogs)");
                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");
                exit;
                }
                # create dialog with timeout
                if ( !create_dialog("B") ) {
                        send_reply("500","Internal Server Error");
                        exit;
                }
                setflag(ACC_DO); # do accounting
        }

So what is wrong in the script?
And I still want to know how to judge a call is "active_dialogs"?
Thanks a lot.
regards,
jing

You need to do this before the create_dialog() call

    Thanks for your reply.But I have another question, I used
     active_dialogs in the cfg file as this:
    if (is_method("INVITE")) {
                    if ($stat(active_dialogs)>=1){
                    sl_send_reply("503", "Service Unavailable");
                    }
    But it seems not right.
    I use sipp to test the limit ,but when the value of
    active_dialogs aim to the number I set ,
    opensips sent 503,but  the value of active_dialogssitll increase.
    So I want to know how the value of this paramer comefrom.
    Or is there something wrong in my cfg document?
    regards,
    Jing

    Very simple, before creating a new dialog check how many open
    dialogs exist.

        hi,Bogdan


         I want to limit the total number of active dialogs ,what
        should I do ?

        I found there are many questions about "Concurrent calls
        limitation " based
        on per user, it's not what I need.

        I appreciate your advice very much,  more detailed the better.

        Thanks,
